Two-masted ships are a type of sailing vessel that have two masts, with the main mast being taller than the mizzen mast. Yawls and ketches are two types of two-masted ships. A yawl is a two-masted sailing vessel with the mizzen mast stepped aft of the rudder post, while a ketch is a two-masted sailing vessel with the mizzen mast stepped forward of the rudder post. Both yawls and ketches are used for recreational sailing and racing.
